  1. 1. Genetic organization of encapsulated and non-encapsulated Haemophilus influenzae strains. Analysis of the glpTQ and 23S rRNA operons

    Författare :Xin-Ming Song; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; intervening sequence; 23S rRNA; transcription; DNA sequence; glpT; Haemophilus influenzae; glpQ; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Encapsulated Haemophilus influenzae type b (Hib) and non-encapsulated H. influenzae (NTHi) are important pathogens causing invasive and mucosal infections in children. A 42 kDa surface-exposed lipoprotein, protein D, has been found to be a potential virulence factor of NTHi. LÄS MER

  3. 2. Mechanisms of cell type-specific gene transcription : studies on the choline acetyltransferase gene

    Författare :Peter Lönnerberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Choline acetyltransferase (ChAT) is the enzyme synthesizing the neurotransmitter acetylcholine. Previous studies from our laboratory on the regulation of the cholinergic phenotype have suggested the presence of regulatory elements in the ChAT gene controlling accurate time- and cell-specific expression.

  4. 3. Development of a recombinant protein vaccine against Plasmodium falciparum malaria

    Författare :Sanjay Ahuja; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Vaccine; Plasmodium falciparum; DBL1alpha ; cross-reactivity; E.coli; recombinant expression; soluble protein;

    Sammanfattning : Malaria, caused by Plasmodium falciparum is one of the world´s deadliest diseases, killing one to two million children, while another 500 million suffer from clinical attacks every year. Infections caused by P. LÄS MER

  5. 4. Homing Endonucleases and Horizontal Gene Transfer in Bacteria and Bacteriophages

    Författare :David Nord; Britt-Marie Sjöberg; Steinar Johansen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dsDNA cleavage; ribonucleotide reductase; GIY-YIG motif; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Homing endonuclease genes (HEGs) are selfish genetic elements that mediate their own super-Mendelian inheritance. This is mediated by the homing endonuclease cleavage of a HEG- allele followed by recombination-repair with a HEG+ allele.The majority of the HEGs are encoded in intervening sequences (IVSs).

  7. 5. Action Potential Generator and Electrode Testing

    Författare :Malcolm Latorre; Karin Wårdell; Göran Salerud; Linda Rattfält; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Design, validation and application of a test platform for electrode characterization and comparison is a problem today. Development of target specific electrodes is increasing, for example surface cloth electrodes, non-contact electrodes, and deep brain stimulation electrodes. LÄS MER
